Improvement in nursing-bottles



UNITED STATES PATENT Orrroiza THOMAS J. MAYALL, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN NURSING-BOTTLES.

Specification forming part of Letters Patent No. 140,5] dated July 1, 1873 application filed June 20, 1873.

To all 'who-m 'it may concern:

Be it known that I, THOMAS J. MAYALL, of Boston, Suffolk county, Massachusetts, have invented certain new and useful Improvements in Stoppers or Gorks for NursingBottles, of which the following is a specification:

My invention consists of au improved cork or stopper for nursing-bottles, constructed as follows, reference being had to the accompanying drawing, which represents a vertical central section of the stopper and the bottle to which the same is applied.

The main or central portion of the stopper is made of wood, glass, or metal formed in the shape represented, with a hole, a, extending through it from end to end 5 a central cylindrical portion, b, turned down to a smaller diameter than the remainder of the stopper, so as to produce the upper and lower ilanges or shoulders c d; a head, e; and top and bottom knobs f g, formed at the extremities of the wooden stem. Around the centra-l cylindrical portion b is snapped or sprung a sleeve, m, of vulcanized India rubber, preferabl y pure rubber, and slightly tapering on the exterior, its smaller end being at the bottom. This sleeve, of proper thickness, is held on the part b by the shoulders c d, between which it nts, and it is the part designed to lit in and close the neck of the bottle, as represented. Upon the upper and lower knobs f g are fitted the ends of the flexible tubes h z', which carry the external mouth-piece j and the internal glass tube k, as usual.

A stopper thus made is cheap, convenient, and admirably adapted for use. The body,

when made of wood, can be readily turned out in one piece in the shape represented, and all that is then needed to fit it for use is to snap or spring the rubber sleeve onto the stem b where it nts, and is securely held between the two shoulders which terminate that sleeve. It can be readily cleaned whenever desired,

and it is but the work voi' a moment to take y oft' and put on the rubber sleeve, as well as the top and bottom tubes h i.

I am aware that rubber tubes have been attached to bulbs or knobs, one at each end ot' a central metallic tubular stem for a nursingbott-le; this I do not claim.

lVhat I claim, and desire to secure by Letters Patent, is-

The liereindescribed stopper for nursingbottles, consisting of a main body or portion formed ot' one piece of wood or other suitable material with top and bottom knobs for attach ment of the liexible suction-tubes, a head by which the stopper can be readily handled, and a central cylindrical stem terminating in two shoulders, upon which stem is sprung a rubber sleeve, clasping said stem and confined between said shoulders and constituting the stopper proper to fit the neck ofthe bottle, as shown and set forth.

In testimony whereof I have signed my name in the presence of two subscribing witnesses.

THOS. J. MAYALL.
